If population doubles and area also doubles in an area, what will happen to density?

Explanation opens after your attempt
Correct Answer

A. घनत्व लगभग समान रहेगाDensity will remain approximately same

Step 1

Concept

If population and area increase in the same ratio, the ratio remains nearly unchanged. Exam tip: use ratio thinking.

Step 2

Why this answer is correct

The correct answer is A. घनत्व लगभग समान रहेगा / Density will remain approximately same. If population and area increase in the same ratio, the ratio remains nearly unchanged. Exam tip: use ratio thinking.

Step 3

Exam Tip

जनसंख्या और क्षेत्रफल समान अनुपात में बढ़ें तो अनुपात लगभग नहीं बदलता। परीक्षा में ratio thinking लगाएं।

Question 3/3 Hard Geography Population Population Density Class 9 Level 75

यदि किसी क्षेत्र का क्षेत्रफल दोगुना हो जाए और जनसंख्या समान रहे तो घनत्व कैसा होगा?

If the area of a region doubles and population remains same what will happen to density?

Explanation opens after your attempt
Correct Answer

A. घनत्व आधा होगाDensity will become half

Step 1

Concept

The same population spreads over larger area so density decreases. Exam tip: remember inverse relation between area and density.

Step 2

Why this answer is correct

The correct answer is A. घनत्व आधा होगा / Density will become half. The same population spreads over larger area so density decreases. Exam tip: remember inverse relation between area and density.

Step 3

Exam Tip

समान जनसंख्या बड़े क्षेत्र में फैलने से घनत्व घटता है। परीक्षा में क्षेत्रफल और घनत्व का उल्टा संबंध याद रखें।
